New to the parlour that day and first day of work ever are quite different.
In different times, I made two contacts via an older message board that led to encounters that were definitely firsts. Both arranged as hotel meets.
I also had a girl from an agency in the NE on what the proprietor told me was her first day ever. As far as she knew, but she was a very straight lady (the proprietor). Also a hotel meet.
I could write an essay on all three meetings.
I also recall a parlour meet, the way it went I suspect it was a first timer but no-one said anything directly; I finished up with a discount off my next visit.
